Rolling Bearings
The HGT Roller Bearings include four main types: Cylindrical Roller Bearings, Tapered Roller Bearings, Thrust Roller Bearings, and Spherical Roller Bearings. These bearings are designed to provide high load capacity, excellent rigidity, and long service life under heavy radial or axial loads. Depending on the type, they can accommodate misalignment, combined loads, and high-speed conditions in industrial machinery, rolling mills, and heavy equipment applications.
Difference between Four Types of Roller Bearings (Cylindrical, Tapered, Thrust, and Spherical Type)
The difference lies in the shape of the rolling elements and the direction of load they can support.
-
Cylindrical Roller Bearings feature cylindrical rollers that make line contact with the raceways. They are ideal for carrying heavy radial loads and allow for high-speed operation.
-
Tapered Roller Bearings use conical rollers that can simultaneously support radial and axial loads. The load capacity increases with the contact angle, making them suitable for combined load applications such as gearboxes and wheel hubs.
-
Thrust Roller Bearings are designed to handle large axial loads in one direction. They can sustain heavy thrust loads with minimal space requirements, commonly used in vertical shafts and heavy-duty presses.
-
Spherical Roller Bearings have barrel-shaped rollers and a spherical raceway, allowing for automatic self-alignment. They can tolerate misalignment and heavy combined loads, making them ideal for mining, steel, and paper industries.
Cylindrical Roller Thrust Bearing
Cylindrical roller thrust bearings are designed to accommodate heavy axial loads while operating at high speed and precision. Their robust construction features cylindrical rollers arranged perpendicularly to the shaft, ensuring uniform stress distribution and exceptional load-carrying capacity. These bearings offer low friction, minimal heat generation, and excellent rigidity, making them ideal for applications requiring stable axial support without radial load capability.

Double row Cylindrical Roller Bearing
Material: GCr15/GCr15SiMn/G20Cr2Ni4A
Type: NNU and NN series cylindrical roller bearing. The NN design has an inner ring with two ribs and an outer ring without ribs.
Double-row cylindrical roller bearings are designed to provide exceptionally high radial load capacity, enhanced rigidity, and stable performance for heavy-duty applications. Featuring two rows of precision-machined cylindrical rollers, this bearing type offers improved load distribution and greater stiffness compared to single-row designs, making it ideal for machinery that demands higher strength and reliability.

Double row Tapered Roller Bearings
Material: GCr15/GCr15SiMn/G20Cr2Ni4A
Features: The double row taper roller bearing is mainly used to support the combined load which is mianly consisted of radial load. It can restrict the axial displacement of the shaft or housing in the two directions and thus can be used as a bidirectional locating bearing.
Application: rolling mills, gearboxes, hoisting equipment, mining machines, tunnelling machines.
Double row tapered roller bearings are engineered to provide exceptionally high radial and axial load capacity, making them ideal for heavy-duty applications that demand strength, stability, and long service life. Featuring two rows of tapered rollers arranged symmetrically, this bearing design distributes loads more effectively than single-row types, offering increased rigidity and superior resistance to overturning moments.

Four-row Cylindrical Roller Bearing
Material: GCr15/GCr15SiMn/G20Cr2Ni4A
Type: FC series cylindrical roller bearing, FCD series cylindrical roller bearing, FCDP series cylindrical roller bearing
Four-row cylindrical roller bearings are engineered for extremely high radial load capacity and superior rigidity, making them the preferred choice for heavy-duty and continuous-operation environments. With four rows of precisely aligned cylindrical rollers, these bearings provide exceptional load distribution, reduced stress concentration, and stable performance even under intense working conditions.

Single row Tapered Roller Bearings
Material: GCr15/GCr15SiMn/G20Cr2Ni4A
Features: Single row tapered roller bearings primarily carry combined loads which is main in radial, and tapered roller bearings with large tapered angle (27°-30°) primarily carry combined loads which is main in axial but nor pure axial loads.
Single row tapered roller bearings are designed to handle combined radial and axial loads with high efficiency, making them one of the most widely used bearing types in industrial and automotive applications. Featuring tapered raceways and rollers positioned at an optimized contact angle, this bearing design ensures precise load distribution, reduced friction, and excellent running stability under varying operating conditions.
